DEFINATION OF RESORPTION:-
Resorption is defined as a condition associated with either a physiologic or pathologic process resulting in loss of dentin, cementum or bone.
Internal resorption is an idiopathic slow or fast progressive resorptive process occuring in the dentin of pulp chamber or in the root canals of the tooth.
- Exact etiology is not known
- Patient often presents with history of trauma or persistent chronic pulpitis, or history of pulpotomy
- Usually asymptomatic , recognized clinically through routine radiograph
- Pain occurs in cases of perforation of root
- Pink tooth is the pathognomic feature of internal root resorption
Clinically:- "pink tooth" appearance
- Radiolucent enlargement of pulp canal.
- Original root canal outline is distorted.
- Bone changes are seen only when root perforation into periodontal ligament takes place.
Pulp tests:- Positive, though coronal portion of pulp is necrotic, apical pulp could be vital.
- Pulp extirpation stops internal root resorption.
- Surgically, treatment is indicated if conventional treatment fails.
